Definitions
- the invention relates to a motor vehicle lock, in particular a side door lock, having a locking mechanism with a rotary latch and at least one pawl, a plastic housing, a lock case, in which an entry area for a lock holder can be formed by means of the plastic housing and the lock case, and a seal, in which the seal is at least is partially assigned to the inlet area.
- motor vehicles are subject to the weather and environmental conditions, from which on the one hand the vehicle driver and the occupant must be protected and on the other hand the components of the motor vehicle must withstand environmental influences.
- Rain, snow, but also flow influences and pressure differences must be compensated or kept as far away as possible from the function of the components.
- the passenger compartment is sealed with a sealing profile between the driver's door and the body, for example.
- Various components of the motor vehicle door are operatively connected to the outside of the motor vehicle on the one hand and to the interior of the motor vehicle on the other.
- a motor vehicle lock installed in a side door of a motor vehicle is engaged in the outside area with a lock holder, for example, whereas another part of the motor vehicle lock can be operatively connected to an internal control, for example.
- the motor vehicle lock is therefore on the one hand subject to external environmental influences and on the other hand has to be located inside the motor vehicle for connection to the inside actuation or an electrical contact are in a dry area.
- DE 20 2008 004 332 U1 discloses a seal which can be used to seal the housing parts of the motor vehicle lock.
- Motor vehicle lock housings are usually designed in two, three or more parts, since on the one hand a proper and easy joining of the functional components must be made possible and on the other hand, for example, manufacturing advantages should be used.
- the disclosed seal comprises a U-shaped receiving chamber, into which a folding element is inserted, so that a meander-shaped seal can be achieved, which can protect the lock housing from ingress of moisture.
- Lines are arranged between the components of the housing of the motor vehicle lock, by means of which the housing protects the mechanical as well as electrical cal components of the motor vehicle lock.
- the components of the motor vehicle lock can be protected in this way from penetrating moisture, which penetrates, for example, through a window seal into the interior of the motor vehicle door.
- the inlet mouth ie in the area of the locking mechanism, which can be brought into engagement with a lock holder
- there is an opening in the motor vehicle lock through which the rotary latch of the locking mechanism can be brought into engagement with the lock holder.
- the motor vehicle lock is preferably formed from a plastic housing and a metal lock case.
- Plastic housing and lock box th preferably enclose the inlet area for the lock holder circumferentially.
- Different Liche solutions have become known as outer seals applied to the motor vehicle lock.
- DE 102016 115 190 A1 discloses a motor vehicle lock with a lock case, the lock case resting against the inner wall of the motor vehicle door in the installation position and a seal sealing the motor vehicle lock against the wall of the motor vehicle door.
- DE 102010032744 A1 also discloses a method in which the lock housing is activated by means of a heat source before a sealing compound is applied and after which the sealing compound is then applied as a seal to the lock housing or the lock case.
- the object of the invention is to provide an improved motor vehicle lock seal.
- it is the object of the invention to minimize the large amount of material used to produce a seal and thus to ensure cost-effective sealing with the same level of tightness, particularly in the area of large bends or sharp contours.
- a motor vehicle lock in particular a side door lock, having a locking mechanism with a rotary latch and at least one pawl, a plastic housing, a lock case, with a means of the plastic housing and the lock case Inlet area for a lock holder can be formed and a seal, wherein the seal is at least partially assigned to the inlet area and the seal is formed from a straight plastic strip material.
- the structure according to the invention of the seal for the motor vehicle lock means that a seal for a motor vehicle lock can now be provided with the lowest possible cost of materials.
- the use of a straight plastic strip offers the possibility of providing a seal for an inlet area of the motor vehicle lock with minimal waste.
- Sealing strips made of plastic can be separated from a plastic pad as a strip, so that waste can only result from a length limitation of the plastic strip.
- the seal is formed from a closed pore elastomeric plastics material.
- the plastic strips can be available as roll material, which can result in further advantages, particularly for assembly.
- the invention speaks of a motor vehicle lock, this also includes those locks that are used in flaps, sliding doors, side doors or covers, wherever environmental influences can have a direct effect on the motor vehicle lock.
- the motor vehicle locksmiths which can also be called locking systems, have a locking mechanism with a rotary case and at least one pawl.
- the locking mechanism can have a first catch and a main catch and/or have an additional blocking lever for at least one pawl.
- the components of the motor vehicle lock are stored or recorded in the housing and/or lock case of the motor vehicle lock.
- An outer surface of the motor vehicle lock is thus formed by the housing and the lock case.
- the lock case encloses the entry opening or the entry area for the lock holder, so that the seal must be used to prevent moisture from penetrating.
- the seal is applied to the lock case and/or the housing of the motor vehicle lock, so that the inlet area can be sealed.
- the seal is primarily located above the inlet area on the vehicle lock.
- the plastic strip can advantageously be designed as a profiled plastic strip, preferably with a rectangular cross section.
- the plastic strip can, for example, be round, oval or square and preferably rectangular.
- the starting material can be in the form of roll material, that is to say as a flat seal, from which plastic strips can then be separated. This allows the plastic strips to be produced inexpensively.
- the mat or roll from which the Kunststoffstrei fen are cut speaks ent in the width of the plastic strips to be produced.
- a means by which the plastic strip can be fastened to the motor vehicle lock is described as an adhesive mask.
- the adhesive mask consists of a carrier material to which an adhesive film is applied and to which the sealing material is bonded. If the plastic strip is now separated from the sealing material or the roll material and the adhesive mask, the carrier material, for example a strip of paper, can be removed from the plastic strip, with the adhesive remaining on the plastic strip. The plastic strip can then be fastened to the motor vehicle lock, that is to say to the housing and to the lock case, by means of the adhesive.
- the use of a plastic mask is a preferred embodiment. However, it is also conceivable that, for example, an adhesive is applied to the motor vehicle lock and the plastic strip is then attached to the motor vehicle lock.
- the plastic strip has a width of 10 mm to 18 mm, preferably a width of 12 mm to 16 mm and even more preferably a width of 15 mm.
- the width of the plastic strip can vary depending on the application, with a thickness of approx. 8-12 mm and preferably 10 mm having turned out to be advantageous.
- the sealing strip must adapt to the contour of the body or lie against it and ensure a tight seal.
- the contour of the motor vehicle lock cannot always follow the contour of the motor vehicle door, so that the gap to be sealed between the motor vehicle lock and the body can vary depending on the installation position. It has been shown that a sufficient gap sealing can be achieved with a width of 10-18 mm, and preferably 15 mm. In particular, a gap between the motor vehicle lock and the body can be securely sealed with the preferred width of the plastic strip.
- the plastic strip is arranged at least in regions around the circumference, thus at least one bend, on the lock case and/or lock housing.
- the plastic strip or sealing strip must securely seal the entry area of the motor vehicle lock against the ingress of moisture. It often happens that the plastic strip is not linear, but also angled extends along the motor vehicle lock, so as to enclose the inlet area at least in some areas. It must be enclosed in such a way that, in particular, the moisture penetrating through a pane seal, for example, cannot reach the inlet area directly due to the force of gravity, but is sealed off by the sealing strip.
- the adhesive strip or the sealing strip can also derive or dissipate the moisture in a targeted manner.
- the sealing strip is preferably to be arranged above a lead-in area of the motor vehicle lock.
- the plastic strip has a notch in an area of the bend, this results in an advantageous embodiment variant of the invention.
- the wider the plastic strip the greater the accumulation of material in the area of the bend.
- this accumulation of material can be reduced and optimally adapted to the bend. In this way, optimal tightness can also be guaranteed in the area where the plastic strip bends, without accumulations of material making assembly difficult, for example.
- an accumulation of material in the area of the bend can also result in the plastic strip detaching from the motor vehicle lock, which makes tight mounting difficult or completely prevents it.
- an accumulation of material in the area of the bend can also result in the plastic strip detaching from the motor vehicle lock, which makes tight mounting difficult or completely prevents it.
- the notch extends to an area in the middle of the plastic strip, a further advantageous embodiment of the invention is achieved.
- the notch With a width of 14 mm, for example, the notch extends about 7 mm into the sealing strip. A remaining area of 7 mm can also be used Sufficient tightness can also be guaranteed in the area of the bend of the plastic strip.
- the notch extends over the entire thickness of the plastic strip, so that bending of the plastic strip is not impeded by additional material in the angled area.
- the notch may have a preferred included angle of 70° to 110°, preferably an included angle of 80° to 100°, and more preferably an included angle of 90°.
- the angles mentioned have proven to be advantageous because, on the one hand, this allows the plastic strip to be bent without material accumulation in the area of the angle and, on the other hand, sufficient tightness can be achieved in the area of the bend.
- the opening angle makes it possible to achieve a bend in the plastic strip of 30° or 40°, for example, but it is also conceivable to create a bend of 90° in the plastic strip, for example, without an accumulation of the sealing material causing the plastic strip to detach from the Motor vehicle lock leads.
- the accumulation of material is present in the remaining area of the notch, it has been shown that the reduced accumulation of material in the angled area enables the plastic strip to be securely mounted on the motor vehicle lock. Even a bend of more than 90° can be realized with the plastic strip according to the invention if, for example, the opening angle is adapted to the bend. A secure sealing of the inlet area of the motor vehicle lock can thus be realized with the least possible waste of the sealing material.
- a further advantageous configuration variant can be achieved if there is a flattening of 1 mm to 5 mm, preferably 2.5 to 3.5 mm, and even more preferably 3 mm, in a notch base.
- the notch is formed by an opening angle of 90°, for example, it being possible for a notch base in the plastic strip to have a flattening of 3 mm, for example.
- the plastic strip can be stabilized due to the flattening in the bottom of the notch of the sealing strip. which in turn leads to increased tightness in the angled area of the plastic strip. In this way, a secure sealing of the motor vehicle lock can be realized and guaranteed with a minimum of material expenditure.
- FIG. 1 shows a three-dimensional view of a motor vehicle lock with a plastic strip attached according to the invention in a three-dimensional view of the plastic strip;
- FIG. 2 shows a three-dimensional view of a partial area of the plastic strip in the initial state with a punched notch and a flattening formed in the base of the notch.
- FIG. 1 shows a motor vehicle lock 1 in a three-dimensional view and detached from a motor vehicle.
- the motor vehicle lock 1 is consequently shown in a position as it is before installation in the motor vehicle.
- the motor vehicle lock 1 comprises a lock case 2, a lock housing 3, a plastic strip 4 and an entry area 5.
- the lock case 2 completely encloses the entry area 5 , the lock case 2 being connected to the lock housing with a clip connection 7 .
- the plastic strip 4 is glued to the lock case 2 and the lock housing 3 as a sealing strip.
- the plastic strip 4 encloses the inlet area 5 at least in sections and in particular the plastic strip 4 protects the inlet area 5 from penetrating moisture, which acts on the motor vehicle lock 1 from the direction of arrow P, for example starting from a window seal.
- the plastic strip 4 is peripherally mounted on the motor vehicle lock 1 in some areas, the plastic strip 4 being provided with two notches 8, 9.
- the notches 8, 9 make it possible for the plastic strip 4 to be mounted in a sealing manner on the motor vehicle lock 1 even in areas of bends 10, 11. In particular, a secure connection of the plastic strip 4 to the motor vehicle lock 1 can be ensured without the plastic strip 4 attaching itself to the motor vehicle lock 1 with increased material stresses.
- By inserting the notch 8, 9 in the plastic strip 4 it is possible for an accumulation of material to build up in the area of the bends 10, 11 and, for example, to hinder or complicate assembly.
- the risk of an independent detachment of the plastic strip 4 from the motor vehicle lock is mini mized, since tension inside the plastic strip 4 is built up or eliminated by the notch 8, 9.
- rivet heads 12, 13, 14, 15 can be seen, by means of which either a connection to the lock housing 3 is established or other components of the motor vehicle lock 1 are mounted and/or held.
- the rivet heads 12, 14 can be provided for be seeking locking parts 6 in the motor vehicle lock 1.
- FIG. 2 shows a partial area of a seal 4 as a plastic strip 4 in a basic embodiment.
- a partial area of the plastic strip 4 is shown in the area of a notch 8, 9, the plastic strip 4 having a cross-sectional area 16 that can be described as rectangular.
- the cross-sectional area 16 is shown as a section through the plastic strip 4.
- the notch 8, 9 in the plastic strip 4 extends to a center line 17 of the plastic strip 4 and extends over the entire thickness D of the plastic strip 4.
- the notch 8, 9 has an opening angle a of 90° in this exemplary embodiment.
- a flattening 19 can be seen in the bottom of the notch 18 , which likewise extends over the entire thickness of the plastic strip 4 .
- the width B of the plastic strip 4 is entered, which can have a width of 15 mm, for example.
- a plastic strip By introducing the notch 8, 9 in the plastic strip 4, it is possible to connect the plastic strip 4 to the motor vehicle lock 1 via a mounting surface 20, which forms a rear side of the plastic strip 4 to be seen in FIG. Of course, the side of the plastic strip 4 facing the viewer can also form the adhesive surface for the plastic strip 4 .
- a plastic strip By introducing the notch 8, 9 in the plastic strip 4, a plastic strip can be produced as a seal with the lowest possible proportion of waste, for example from a roll of material, resulting in cost-effective production of the plastic strip 4 as a seal for the motor vehicle lock 1.
